Circulators

Circulator

We have an extensive range of circulator designs for many different market sectors.

We have chosen a selection of these due to their popularity for our standard product range and these can be supplied with additional options if required. Many customers have found it beneficial to have one or more of the following options:

  • integrated power monitors
  • phase matching
  • integrated heat-sink

The tables below show a selection of our standard product range but if you can't see a circulator design that meets your requirements then please contact our sales office who will be pleased to advise you on any possible solutions we can offer.
